JMS Server: Monitoring: Active Connections:
Sessions

Use this page to monitor session information for a JMS connection. A
session defines a serial order for both the messages produced and the
messages consumed, and can create multiple message producers and message
consumers. The same thread can be used for producing and consuming
messages.

To drill down for more detailed information about the session's
consumers and producers, click the hyperlinked number for the specific
consumer or producer that you want to monitor.
